Gratin De Courgettes

Instructions

1. Preheat your oven to 375°F (190°C). Grease a baking dish with butter or non-stick cooking spray.

2. In a large skillet, melt the butter over medium heat. Add the chopped onion and minced garlic. Sauté for a few minutes until the onion is soft and translucent.

3. Add the thinly sliced zucchinis to the skillet. Season with salt and pepper. Cook for about 5-7 minutes, stirring occasionally, until the zucchinis are tender. Remove from heat.

4. In a separate saucepan, melt the remaining butter over medium heat. Stir in the flour to create a roux. Cook for a minute, stirring constantly.

5. Slowly pour in the milk while whisking continuously to avoid lumps. Cook the sauce until it thickens and becomes creamy.

6. Remove the saucepan from the heat and stir in half of the grated Gruyere cheese until it's melted and well combined.

7. Arrange half of the cooked zucchinis in the greased baking dish. Pour half of the creamy sauce over the zucchinis. Repeat the layers with the remaining zucchinis and sauce.

8. Sprinkle the top of the gratin with the remaining Gruyere cheese and grated Parmesan cheese.

9. Bake the Gratin De Courgettes in the preheated oven for about 25-30 minutes, or until the top is golden brown and bubbly.

10. Once baked, remove the gratin from the oven and let it sit for a few minutes before serving. Garnish with chopped fresh parsley for a pop of color and added freshness.
